CARE AND CLEANING
WARNING Concerning Stationary Images on the TV
Screen:
Do not leave stationary or letterbox images on screen
for extended periods of time. This can cause uneven
picture-tube aging.
Normal use of the TV should involve the showing of pictures
that contain constantly moving and changing images that fill the
screen. Be careful not to leave nonmoving images on screen
for extended periods of time, or to display the same images on
screen too frequently, because subtle ghost images can be left
on the picture tubes. Sources of stationary images may be
DVD disks, laser disks, video games, CD-i disks, videotapes,
digital television boxes, broadcast channels, cable channels,
satellite channels, and others. Here are some examples of
stationary images (this is not an all-inclusive list; you
may encounter others in your viewing):
DVD menus—listings of DVD disk content
Letterbox black bars—shown at the top and bottom of
the TV screen when a wide screen (16:9) movie is viewed
on a TV with standard (4:3) aspect ratio.
Video-game images and scoreboards
Television station logos—present a problem if they are
bright and stationary; moving or low-contrast graphics are
less likely to cause uneven aging of the picture tube
Stock-market tickers—presented at the bottom of the
TV screen
Shopping channel logos and pricing displays—bright
and shown constantly or repeatedly in the same location on
the TV screen.

LACEMENT OF THE TV
To avoid cabinet warping, cabinet color changes, and
increased chance of set failure, do not place the TV where
temperatures can become excessively hot; for example, in
direct sunlight or near a heating appliance.
Be sure to allow a free flow of air to and from the perforat-
ed back cover of the set.
CLEANING
To avoid possible shock hazard, be sure the TV is unplugged
from the electrical outlet before cleaning.
Regularly dust the TV with a dry, nonscratching duster to
keep the TV clean.
•When cleaning the TV, take care not to scratch or damage
the screen surface. Avoid wearing jewelry or using anything
abrasive. Do not use household cleaners. Wipe the front
screen with a clean cloth dampened with water. Use even,
easy, vertical strokes when cleaning.
Gently wipe the cabinet surfaces with a clean cloth or
sponge dampened in a solution of cool, clear water and a
mild soap or detergent. Use a clean, dry cloth to dry the
wiped surfaces.
Occasionally vacuum the ventilation holes or slots in the
back cover of the set.
Never use thinners, insecticide sprays, or other chemicals on
or near the cabinet, as they might cause permanent marring
of the cabinet finish.
